JOHN W. LAMBERT, OF ANDERSON, INDIANA, ASSIGNOR TO THE BUCKEYE MANUFACTURING OQMPANY, OF SAME PLACE.

GAS-ENGINE CYLINDER.

SPECIFICATION forming part of Letters ratent No. 640,6 7, dated January 2, ieoo. Application filed May 13, 1899. Serial No. 716,736. (No model.)

To to whom, it may concern:

Be it known that I, JOHN W. LAMBERT, a citizen of the United States, and a resident of Anderson, county of Madison, State of Indiana, have invented certain new and useful Improvements in Gas-Engine Cylinders, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figures 1 and 2 respectively represent longitudinal perspective views of the two preferred forms of my present invention.

This invention has particular reference to that class of gas-engine cylinders covered by my patent of December 3, 1895, No. 550,832, in which provision is made for the removal of the head of the water-j acket independently of the cylinder proper and its sparker-plate, whereby the necessity of packing the jackethead against explosive pressure is avoided,

the lime incrustation may be readily removed without disturbing the other parts of the cylinder or engine, and the end of the cylinder in which the explosion takes place is more effectively cooled 3 and the invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

Referring to the drawings by numerals, 1 designates the cylinder proper, and 2 the water-jacket enveloping the same. Near the open end of the cylinder it is provided with an exterior integral flange 3, extending entirely around the cylinder and rabbeted on its inner face, as at at. The forward end of the jacket has an outward-extending annular flange which fits into the rabbet at, suitable bolts 5 being employed to clamp the jacket in place. The rear end of the jacket is provided with an inward-extending annular flange 6, which rests in an exterior rabbet or groove formed in the outer edge of the head of the cylinder, the rear end of the jacket coming flush with the cylinder-head. In Fig. 1 the cylinder is provided with a sparker-passage 7, centrally through its head, the head of the cylinder being double-walled, the inner wall 8 being connected to the outer wall 9 by the tube which forms said sparker-passage, and the walls of the head and the connecting-tube being integral with each other and the main part of the cylinder. This construction is advantageous in that it provides for cooling the cylinder thoroughly around the sparkerpassage, where the cooling effect is most needed, and, further, in that it is at the same time easily manufactured. The essential feature of the invention, however, lies in the arrangement of the jacket. It will be observed that a jacket of this construction may be fastened securely in place by but a single series of bolts used at the open end, leaving the rear end entirely free ofsbolt-holes and bolts, which is desirable not only on the score of economy, but also because of neatness and simplicity of appearance. It will also be observed that the removal of the entire jacket may be readily accomplished without disturbing the sparker devices, whereby the entire inner surface of the walls of the water-charm ber may be readily gotten at for the purpose of removing the lime deposit that forms when hard water is used as the cooling medium, and it will be observed that these desirable results are accomplished without being required to pack the joints against anything but the water-pressure, which is so slight as to require but an exceedingly light packing. It will also be observed that the inwardturned flange at the rear end of the jacket is comparatively narrow, the drawings showing it terminating about in the plane of the exterior of the cylinder, the flange on the cylinder-head extending outward but slightly beyond the plane of said exterior wall of the cylinder. The object of this is to obtain the maximum of rigidity and strength with the lightest possible jacket, it being evident that were the flange 6 made deeper or wider the jacket would have to be of heavier metal in order to stand the strain incident to clamping it in place from the rear end of the cylinder.

In Fig. 2 the head of the cylinder is singlewalled, the sparker opening being formed preferably at some point along the side of the cylinder.

I claim-=- 1. In a gas engine cylinder, the combination of a cylinder proper having an exterior flange at its forward end and a rabbet at its rear closed end, and a-removable water-jacket en- 10o flange and its rear flanged end engaging said rabbet, as and for the purposes set forth.

2. In a gas-engine cylinder, the combination of a cylinder, having an exterior annular flange at its rear end and an exterior flange at its forward end, and a removable jacket encircling the cylinder between said flanges, said jacket having an outward-turned flange at its forward end engaging the forward flange of the cylinder and an inward-turned flange at its rear end engaging the rear flange of the cylinder, and a series of bolts clamping the two forward flanges together, as and for the purposes set forth.

3. In combination with a gas-engine cylinder having an exterior annular flange at its open end and a double-walled head at its JOHN W. LAMBERT.
